FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. $12,927, dated October 15, 1889. Application filed March 29, 1889- Serial No. 305,211. (No model.)

ToaZZ whom, it may concern:

Be it known that I, FREDERICK D. LANGEN- HEIM, a citizen of the United States, anda resident of the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Feedater Heaters, of which the following is a true and exact description, due reference being had to the drawings which accompany and form part of this specification, and in which similar letters denote similar parts.

My invention relates to that class of feed or furnace to the stack through which the waste products of combuston are carried off. 13 represents a frame-work in this flue, having cross-beams b b Z1 b at different levels. On these beams are placed water receptacles C C (J C 0, preferably cylindrical in shape and made of light boiler-iron or any other proper material. As may be seen, these receptacles are arranged above each other and staggered.

D is the inlet water-pipe from the source of supply, and E the outletpipe from the heater to the boiler.

c are the brackets upon which the water receptacles of the heater are placed and through which they are secured to the beamsb b 19 F, F, F and F are pipes leading from one receptacle to the other.

G are blow-off pipes, and g the connections for the blow-oif pipes with the waterrecep-- tacles.

The water-receptacles G C C (J C are preferably made of size sufficient to admit their being entered and cleaned.

The operation is as follows: The water enters through the inlet-pipe D and passes through. the receptacles C. It then passes by the pipe F to the receptacle 0, returning through said receptacle to its end, then through pipe F to receptacle 0 then through receptacle 0 to its end, then through pipe F to receptacle 0 then through receptacle 0 then through the pipe F to receptacle 0 then through receptacle (3 to its end, and then through outlet-pipe E to the boiler.

By my improved construction the water is passed through a series of large receptacles, which practically act as settling-tanks, and at the same time the water is highly heated. Again, this construction causes the receptacles to be in different planes, and there fore all the waste products of combustion act upon the water to be heated. Again, the position of the receptacles in relation to each other being staggered, they are more completely acted upon by the products of com bustion.

I do not intend to limit myself to any spe cific number of receptacles, as they mayvary in number from that shown in the drawings; nor do I intend to limit myself to the exact arrangement of receptacles shown in the drawings.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-= 1. A feed-water heater consisting of a nuinber of drums arranged one above the other, pipes connecting said drums at their ends in a continuous series, said pipes being located above the bottoms of the drums, so that the lower portions of the latter shall serve as settling-chambers, a water-exit pipe leading from the last or uppermost drum of the series, and a water-supply pipe leading to the first or lowermost drum thereof, substantially as described.

2. A feed wat-er heater consisting of a number of drums arranged one above the other, pipes connecting said drums at their ends in a continuous series, said pipes being located above the bottoms of the drums, so that the lower portions of the latter shall serve as settling-chambers, awater-exit pipe leading from the last or uppermost drum of the series, and a Water-supply pipe leading to the first or lowermost drum thereof, and blow-off pipes at the bottom of the several drums, substantially as described.

3. The combination, with the flue A, of cross-pieces or girders one above the other therein, saddles 6, located upon said girders, and a series of drums supported in said saddles and connected end to end in a continuous series and provided with a water-supply pipe and a Water-exit pipe, substantially as described.

4. A feed-Water heater consisting of a number of drums located in pyramid arrangement Within a heating-flue, a Water-supply I 5 pipe connected to one of the lower drums and a Water-exit pipe to the uppermost drum, and pipes connecting said drums in a continuous series, said pipes opening" into the heads of the drums at substantially the center of said heads, substantially as described.

In testimony of which invention I have hereunto set my hand, atPhiladelphia, Pennsylvania, this 25th day of March, A. D. 1889.
